Description

Technical Field

[0001] This invention relates to the field of air-supported membrane architecture, and more specifically, to a PVDF (polyvinylidene fluoride) membrane chamber and construction method for sand and gravel systems in high-altitude, dry, hot, windy valleys. Background Technology

[0002] High-altitude hot and dry valleys refer to river valley areas characterized by high temperatures and low humidity, mostly distributed in tropical or subtropical regions. These areas are rich in sunlight and heat resources, have thick soil layers, but sparse vegetation. The sand and gravel processing system is the "granary" of the power plant's core structure, responsible for producing concrete aggregate. Sand and gravel processing systems used in power plant construction are large-scale, high-standard, and have tight construction schedules. To facilitate large-scale sand and gravel processing and save on construction costs and time, air-supported membrane structures are generally the preferred choice.

[0003] Air-supported membrane structures refer to a building structure system that uses special architectural membrane materials as the outer shell or roof, and is equipped with an intelligent electromechanical system that provides positive air pressure inside the structure to support the main body. Air-supported membrane structures are characterized by large span and flexibility, and can be customized for large-scale sand and gravel processing systems, while also helping to reduce dust emissions.

[0004] To provide a more comfortable processing environment, the air-supported membrane structure uses insulation cotton and other materials between the two air-supported membrane layers to achieve a thermal insulation effect. However, the existing assembly method of the insulation layer and the air-supported membrane layer is prone to slippage due to wind force in places with complex and variable wind fields, such as high-altitude dry and hot valleys, resulting in poor thermal insulation performance of the air-supported membrane structure. Summary of the Invention

[0005] This invention discloses a PVDF membrane storage system and construction method for sand and gravel systems in high-altitude, dry, hot river valleys with strong winds, in order to solve the technical problem in the prior art where the insulation layer is directly inserted into the interlayer at the top of the air-supported membrane wall, and is prone to sliding relative to the top of the air-supported membrane wall due to wind swaying, resulting in poor insulation performance.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] This application provides embodiments of a PVDF membrane storage system for sand and gravel systems in high-altitude, hot, dry valleys with strong winds, comprising: a concrete foundation, an air-supported membrane roof, and an insulation layer. The air-supported membrane roof is anchored to the concrete foundation. The air-supported membrane roof includes an inner roof layer and an outer roof layer, with a cavity formed between the inner and outer roof layers. The insulation layer is disposed within the cavity. The insulation layer includes an insulation body, a support member, and a pull rope. The support member is disposed within the insulation body. The pull rope is connected to the support member. The pull rope can pull the support member to switch between a first state and a second state. In the first state, the dimension of the support member in the width direction of the insulation body is smaller than the width of the insulation body, and at least partially, the edges on both sides of the insulation body in the width direction are bendable. In the second state, the support member can abut against both sides of the insulation body in the width direction, supporting the insulation body to unfold in the width direction of the insulation body.

[0008] In some embodiments, the pull cord has a first cord and a second cord arranged along the extension direction of the support member. The first cord is slidably engaged with a first end of the support member and fixedly connected to a second end of the support member. The second cord is slidably engaged with a second end of the support member and fixedly connected to a first end of the support member. The first cord and the second cord can pull the support member to bend elastically, thereby supporting the insulation body to unfold in the width direction of the insulation body.

[0009] In some embodiments, the support member includes a first rod and a second rod, with the two ends of the first rod corresponding one-to-one with the two ends of the second rod and rotatably connected to form the two ends of the support member.

[0010] In some embodiments, the support includes a connector. The ends of the first rod and the second rod are rotatably connected via the connector. The connector has a wire hole. Both the first rope and the second rope pass through the wire hole, and one of the first rope and the second rope is fixedly connected to the connector, while the other is slidably engaged with the connector.

[0011] In some embodiments, the connector further includes a locking bolt and a locking nut. The locking bolt passes through the wall of the through-hole. The locking bolt has a positioning hole. A first rope or a second rope passes through the positioning hole. The locking nut is threaded into the locking bolt to secure the first rope or the second rope to the connector by turning the locking nut.

[0012] In some embodiments, both the first rod and the second rod are glass fiber tubes.

[0013] In some embodiments, both the first rope and the second rope are steel wire ropes with an outer rubber layer.

[0014] In some embodiments, the insulation body has a mounting cavity for mounting a support member. The width of the mounting cavity gradually decreases along the direction from the middle of the support member to its end.

[0015] In some embodiments, the support member is pre-bent within the insulation body, and the support member can switch to a first state under the action of the bending elasticity of the support member.

[0016] In some embodiments, the insulation layer further includes a rope tube, which is fixedly disposed on the insulation body along the extension direction of the insulation layer and sleeved on the pull rope.

[0017] In some embodiments, the insulation layer includes multiple support members. The support members are spaced apart along the extension direction of the insulation layer, and the pull rope is connected to each support member in sequence.

[0018] In some embodiments, the PVDF membrane chamber of the sand and gravel system includes multiple inner wall tops, each inner wall top having a first connecting portion and a second connecting portion on both sides in the width direction. The first connecting portion is connected to the inner wall of the outer wall top, and the second connecting portion is connected to the second connecting portion of the adjacent inner wall top.

[0019] In some embodiments, the width of the second connection is equal to the thickness of the insulation layer.

[0020] On the other hand, this application also provides a construction method for a PVDF membrane storage chamber in a sand and gravel system. This construction method for a PVDF membrane storage chamber in a sand and gravel system can be used for PVDF membrane storage chambers in high-altitude, dry, hot valleys with strong winds, as provided in this application. The construction method for the PVDF membrane storage chamber in a sand and gravel system includes:

[0021] Step 1: Pour a concrete foundation with an anchoring structure for securing the top edge of the air-supported membrane wall.

[0022] Step 2: Lay the protective layer on top of the air-supported membrane wall;

[0023] Step 3: Deploy the air-supported membrane structure on the protective layer at the top of the air-supported membrane structure;

[0024] Step 4: Fix the edge of the air-supported membrane wall to the anchoring structure of the poured concrete foundation.

[0025] Step 5: Inflate the space formed by the top of the air-supported membrane wall, the poured concrete foundation, and the ground.

[0026] Step 6: Insert the insulation layer into the cavity formed between the inner and outer layers of the air-supported membrane wall.

[0027] Step 7: Secure both ends of the insulation layer;

[0028] Step 8: Pull the cord of the insulation layer to switch the support inside the insulation layer from the first state to the second state.

[0029] The technical solution adopted in this invention can achieve the following beneficial effects:

[0030] In the PVDF membrane chamber of the high-altitude, hot, dry valley, windy area sand and gravel system provided in this application, the insulation layer is assembled into the receiving cavity between the inner and outer membrane walls after being supported by the membrane roof. This helps reduce the volume of a single membrane unit and facilitates the deployment and installation of the membrane roof. Furthermore, the dimensions of the support members within the insulation layer in the width direction can be adjusted via pull ropes, thereby adjusting the rigidity of the insulation layer in the width direction. Specifically, during the assembly of the insulation layer between the inner and outer membrane walls, the dimensions of the support members in the width direction of the insulation layer can be reduced to facilitate installation. After the insulation layer is assembled between the inner and outer membrane walls, the dimensions of the support members in the width direction of the insulation layer can be increased to ensure that the insulation layer remains in an expanded state in the width direction at all times. Therefore, this solution helps the insulation layer overcome its own weight and the shaking of the air-supported membrane wall top under wind force, so that the two sides of the insulation layer in the width direction can abut against the two sides of the receiving cavity in the width direction of the insulation layer, so as to ensure that the insulation layer can cover the top of the air-supported membrane wall, and improve and maintain the insulation effect of the sand and gravel system PVDF membrane chamber.

Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0053] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0054] The following is in conjunction with the appendix Figures 1 to 18 This paper provides a detailed description of the PVDF membrane storage system and construction method for sand and gravel systems in high-altitude dry and hot valley windy areas, based on specific embodiments and application scenarios.

[0055] Reference Figures 1 to 3 The PVDF membrane structure for a sand and gravel system in a high-altitude, hot, dry valley with strong winds provided in this application includes a concrete foundation 100, an air-supported membrane roof 200, and an insulation layer 300. The concrete foundation 100 is a basic structural component that provides an installation and load-bearing foundation for other components. The air-supported membrane roof 200 is the membrane structure that forms the walls and roof of the air-supported structure.

[0056] Reference Figure 1 The air-supported membrane wall top 200 is anchored to the concrete foundation 100. For example, the concrete foundation 100 can be a retaining wall, foundation, or ring beam formed by reinforced concrete casting. Specifically, the air-supported membrane wall top 200 can be connected using the existing anchoring structure between the membrane edge and the foundation in air-supported membrane structures. Therefore, this embodiment will not elaborate on the connection structure between the air-supported membrane wall top 200 and the concrete foundation 100.

[0057] Reference Figure 2 and Figure 3 The air-supported membrane roof 200 includes an inner roof 210 and an outer roof 220. A receiving cavity 201 is formed between the inner roof 210 and the outer roof 220. An insulation layer 300 is disposed within the receiving cavity 201. Exemplarily, the insulation layer 300 is laid flat on the outer roof 220 along its extending direction and covers the receiving cavity 201. Exemplarily, the outer roof 220 can be, but is not limited to, a PVDF membrane. Specifically, the outer roof 220 can be a PVDF membrane used in air-supported membrane structures in the prior art.

[0058] Reference Figure 5 The insulation layer 300 includes an insulation body 310, a support member 320, and a pull rope 330. The support member 320 is disposed within the insulation body 310. For example, the support member 320 is a supporting frame for the insulation body 310, mainly used to support the insulation body 310 so that it can remain in an extended state in the width direction. For example, Figure 5 The y-axis indicates the width direction of the insulation body 310, and the x-axis indicates the extension direction of the insulation body 310. Specifically, the support member 320 is made of a material with a harder hardness than the insulation body 310, so that the support member 320 can provide support for the insulation body 310. Exemplarily, the support member 320 can be a metal or non-metal frame. In some optional embodiments, the support member 320 is a frame made of elastic steel. In some embodiments, the support member 320 is a frame made of glass fiber tube.

[0059] Reference Figure 5 and Figure 7 The pull rope 330 is connected to the support member 320. The pull rope 330 can pull the support member 320 to switch between a first state and a second state. Specifically, the pull rope 330 can cause the support member 320 to elastically deform, allowing the support member 320 to switch between a first state and a second state.

[0060] Figure 5 and Figure 7The diagram illustrates the support member 320 switching to a first state in some embodiments. For example, when the support member 320 is in the first state, its dimension in the width direction of the insulation body 310 is smaller than the width of the insulation body 310, and at least partially, the edges on both sides of the insulation body 310 in the width direction are bendable. It should be noted that the insulation body 310 is made of a flexible material. Specifically, the insulation body 310 can be, but is not limited to, made of fabric and / or insulation cotton. Therefore, when the dimension of the support member 320 in the width direction of the insulation body 310 is smaller than the width of the insulation body 310, at least partially, the edges of the insulation body 310 in the width direction are not supported by a relatively rigid support member 320. Therefore, when the insulation body 310 is subjected to external force in the width direction, the edges of the insulation body 310 can deform. Specifically, during the installation of the insulation layer 300, the support member 320 can be switched to the first state by pulling the rope 330. This makes it easier to insert the insulation layer 300 into the receiving cavity 201, thereby reducing the difficulty of inserting the insulation layer 300 into the receiving cavity 201.

[0061] Figure 8 and Figure 9 The diagram illustrates the second state of the support member 320 in some embodiments. When the support member 320 is in the second state, the support member 320 can abut against both sides of the insulation body 310 in the width direction and support the insulation body 310 to unfold in the width direction of the insulation body 310.

[0062] It should be noted that, due to the influence of gravity during installation, the 300mm insulation layer is prone to issues such as… Figure 2 The shape is as shown in the diagram. Furthermore, the insulation layer 300 itself has relatively poor hardness, making its edges prone to folding or bending deformation. Therefore, after the insulation layer 300 passes through the receiving cavity 201, it can easily result in the receiving cavity 201 not being filled on both sides in the width direction of the insulation layer 300, leading to a portion of the top 200 of the air-supported membrane wall not being covered by the insulation layer 300 and resulting in poor insulation performance.

[0063] In the PVDF membrane silo system of the sand and gravel system provided in this application, after the insulation layer 300 is inserted into the receiving cavity 201, the support member 320 can be switched to a second state by pulling the rope 330. In this way, the two sides of the insulation layer 300 in the width direction can be abutted against the two sides of the receiving cavity 201 in the width direction under the support of the support member 320, thus preventing the receiving cavity 201 from being unfilled on both sides of the insulation layer 300 in the width direction, thereby improving the insulation performance of the PVDF membrane silo system of the sand and gravel system. Furthermore, after the PVDF membrane silo system of the sand and gravel system is built, the top 200 of the air-supported membrane wall will vibrate due to wind forces from different directions. In the PVDF membrane silo system of the sand and gravel system provided in this application, the support member 320 can provide support for the insulation layer 300, preventing the width dimension of the insulation layer 300 from decreasing due to external vibration or gravity, thereby helping to maintain the insulation performance of the PVDF membrane silo system of the sand and gravel system.

[0064] In some embodiments, a pull rope is pre-installed inside the receiving cavity 201. For example, the pull rope passes through both ends of the receiving cavity 201. During the installation of the insulation layer 300, one end of the insulation layer 300 is connected to the pull rope, and the insulation layer 300 is pulled through the receiving cavity 201 by the pull rope.

[0065] Reference Figure 1 In some embodiments, the air-supported membrane top 200 has a plurality of sequentially arranged receiving cavities 201, and the projection of the receiving cavities 201 onto the outer wall top 220 can cover the outer wall top 220. This is beneficial in that the insulation layer 300 inside the receiving cavity 201 can cover the air-supported membrane top 200, thereby improving the insulation performance of the PVDF membrane chamber in the sand and gravel system.

[0066] In some embodiments, reference is made to Figure 2 and Figure 3 The width of the inner wall top 210 corresponding to each receiving cavity 201 is the first width. The width of the outer wall top 220 corresponding to each receiving cavity 201 is the second width, and the first width is greater than the second width. Specifically, as follows... Figure 2 As shown, after the insulation layer 300 is located in the receiving cavity 201, it can be attached to the inner wall top 210. In this way, a cavity is formed between the insulation layer 300 and the outer wall top 220. This helps to reduce the heat exchange rate between the outdoor side and the indoor side of the air-supported membrane wall top 200, thereby improving the insulation effect of the air-supported membrane building.

[0067] In addition, in the above embodiment, the insulation layer 300 adheres to the inner wall top 210 under the action of gravity, which allows the support member 320 to form an arc-shaped structure adapted to the inner wall top 210, thereby facilitating the generation of elastic force in the width direction of the insulation layer 300 by the support member 320. Therefore, in this embodiment, the support member 320 can provide a pre-tightening force to stop the insulation layer 300 in the width direction and the two sides of the receiving cavity 201 in the width direction, thereby preventing the insulation layer 300 from sliding relative to the inner wall top 210 in the width direction and ensuring that the insulation layer 300 can cover the air film wall top 200.

[0068] In some embodiments, reference is made to Figure 12 and Figure 13 The pull cord 330 has a first cord 331 and a second cord 332 arranged along the extension direction of the support member 320. For example, the extension direction of the support member 320 can be the extension direction of the insulation body 310. The first cord 331 is slidably engaged with a first end of the support member 320 and fixedly connected to a second end of the support member 320. The second cord 332 is slidably engaged with a second end of the support member 320 and fixedly connected to a first end of the support member 320. The first cord 331 and the second cord 332 can pull the support member 320 to elastically bend, thereby supporting the insulation body 310 to unfold in the width direction of the insulation body 310.

[0069] Specifically, after the insulation layer 300 is inserted into the receiving cavity 201, the first rope 331 can be pulled along the first extending direction of the support member 320, and the second rope 332 can be pulled simultaneously along the second extending direction of the support member 320. This causes the support member 320 to elastically deform in the width direction of the insulation body 310, supporting the insulation body 310 to expand in the width direction of the insulation body 310 and abutting against both sides of the receiving cavity 201 in the width direction of the insulation body 310. The first extending direction of the support member 320 is the direction from the end of the support member 320 fixedly connected to the first rope 331 to the end of the support member 320 that slides with the first rope 331. The first extending direction of the support member 320 is opposite to the second extending direction of the support member 320.

[0070] In addition, in the above embodiments, the first rope 331 and the second rope 332 can provide elastic deformation force for the support member 320, and can also guide the end of the support member 320 through sliding fit, which is beneficial to constrain the elastic deformation of the support member 320 in the width direction of the insulation body 310.

[0071] In some embodiments, reference is made to Figure 12 and Figure 13The support member 320 includes a first rod 321 and a second rod 322. The two ends of the first rod 321 correspond one-to-one with the two ends of the second rod 322 and are rotatably connected to form the two ends of the support member 320. Specifically, the first end of the first rod 321 corresponds to and is rotatably connected to the first end of the second rod 322. The second end of the first rod 321 corresponds to and is rotatably connected to the second end of the second rod 322. (Refer to...) Figure 13 In some embodiments, the first rod 321 and the second rod 322 are symmetrically distributed on opposite sides of the pull rope 330. Specifically, by pulling the first rope 331 and the second rope 332, the middle parts of both the first rod 321 and the second rod 322 can undergo elastic deformation.

[0072] In some embodiments, reference is made to Figure 7 and Figure 9 The support member 320 includes a connector 323. The ends of the first rod 321 and the second rod 322 are rotatably connected by the connector 323.

[0073] Reference Figure 16 and Figure 17 The connector 323 has a wire passage hole 3231. Both the first rope 331 and the second rope 332 pass through the wire passage hole 3231, and one of the first rope 331 and the second rope 332 is fixedly connected to the connector 323, while the other is slidably engaged with the connector 323. For example, the first rope 331 and the second rope 332 share the same wire passage hole 3231 to reduce the distance between them, which helps to reduce the torque on the support member 320 and improves the reliability of the assembly between the support member 320 and the insulation body 310.

[0074] Reference Figures 15 to 18 The connector 323 also includes a rope locking bolt 3232 and a rope locking nut 3233. The rope locking bolt 3232 passes through the wall of the wire through hole 3231. The rope locking bolt 3232 has a positioning hole 3234. The first rope 331 or the second rope 332 passes through the positioning hole 3234. The rope locking nut 3233 is threadedly engaged with the rope locking bolt 3232 to secure the first rope 331 or the second rope 332 to the connector 323 by turning the rope locking nut 3233. Exemplarily, the rope locking nut 3233 is a cap nut. This embodiment is beneficial in preventing the end of the rope locking bolt 3232 from damaging the insulation body 310.

[0075] Reference Figure 14 and Figure 18 The connector 323 includes a main structure 3235, a first socket portion 3236, and a second socket portion 3237. The first socket portion 3236 and the second socket portion 3237 are symmetrically arranged on opposite sides of the main structure 3235. Specifically, the first socket portion 3236 is fitted onto the end of the first rod 321. The first socket portion 3236 is fitted onto the end of the second rod 322. (Refer to...) Figure 18 The first socket 3236 and the second socket 3237 are both rotatably connected to the main structure 3235 via a rotating shaft 3238.

[0076] In some alternative embodiments, both the first rod 321 and the second rod 322 are glass fiber tubes.

[0077] In some embodiments, both the first rope 331 and the second rope 332 are steel wire ropes with an outer rubber layer.

[0078] In some embodiments, the insulation body 310 has a mounting cavity 311 for mounting a support member 320. The width of the mounting cavity 311 gradually decreases along the direction from the middle of the support member 320 to its end. Exemplarily, the length of the mounting cavity 311 in the extending direction of the insulation body 310 is less than the length of the support member 320. Specifically, the support member 320 can be bent and deformed under the constraint of the cavity wall of the mounting cavity 311, so that the insulation body 310 can constrain the bending shape of the support member 320 and generate a preload. Exemplarily, such as... Figure 5 As shown, the support member 320 can be formed into a near-rhomboid shape under the constraint of the mounting cavity 311 of the insulation body 310. Specifically, the middle portion of the first rod 321 deforms away from the second rod 322. The middle portion of the second rod 322 deforms away from the first rod 321. The pull rope 330 is located between the first rod 321 and the second rod 322.

[0079] In some embodiments, the support member 320 is pre-bent and disposed within the insulation body 310, and the support member 320 can switch to a first state under the action of the bending elasticity of the support member 320.

[0080] In the above embodiments, the mounting cavity 311 helps to constrain the pre-bending of the support member 320, thereby guiding the bending deformation of the support member 320 under the pull of the rope 330, and enabling the support member 320 to bend in a predetermined direction. In addition, the elasticity generated by the support member 320 can be used to allow the insulation layer 300 to extend in its extension direction, and the elasticity of the support member 320 itself can be used to return it to the first state.

[0081] For example, the mounting cavity 311 can be formed by connecting the multi-layered structures in the insulation body 310 together by stitching and / or heat fusion.

[0082] Reference Figure 5 and Figure 6 In some embodiments, the mounting cavity 311 has a first rod cavity 3111, a second rod cavity 3112, and a rope cavity 3113, wherein the first rod 321 is slidably disposed within the first rod cavity 3111. The second rod 322 is slidably disposed within the second rod cavity 3112. The pull rope 330 is slidably disposed within the rope cavity 3113.

[0083] Reference Figure 6 The insulation body 310 has a first seam edge 3121, a second seam edge 3122, and a third seam edge 3123. Exemplarily, the first seam edge 3121 is disposed adjacent to the edge of the insulation body 310 in the width direction, and the first seam edge 3121 is substantially parallel to the edge of the insulation body 310 in the width direction. (Refer to...) Figure 8 When the support member 320 is in the second state, the middle portion of the first rod 321 and the middle portion of the second rod 322 abut against the first seam edge 3121, thereby constraining the middle portion of the first rod 321 to be substantially parallel to the edge of the insulation body 310 in the width direction. The second seam edge 3122 is connected to the first seam edge 3121, and the second seam edge 3122 is inclined relative to the first seam edge 3121 towards the middle portion of the insulation body 310 in the width direction. (Refer to...) Figure 8 When the support member 320 is in the second state, the first rod 321 and the second rod 322 can be basically in contact with their corresponding first seam edge 3121 and second seam edge 3122.

[0084] Reference Figure 5 and Figure 6 The third suture edge 3123 is located between the first rod cavity 3111 and the second rod cavity 3112, which helps to constrain the deformation range of the first rod 321 and the second rod 322.

[0085] In the above embodiments, the first rod cavity 3111 and the second rod cavity 3112 can be formed by enclosing at least two layers of structure, including the first seam edge 3121, the second seam edge 3122, the third seam edge 3123, and the insulation body 310. This design helps to constrain the deformation of the support member 320, allowing the support member 320 to elastically deform in a predetermined manner. This is beneficial for improving the effect of the support member 320 on the insulation body 310 as it unfolds along the width direction of the insulation body 310. The rope cavity 3113 can constrain the extension path of the pull rope 330, thus helping to avoid redundancy or knotting of the pull rope 330.

[0086] In some embodiments, the insulation layer 300 further includes a rope passage tube 340, which is fixedly disposed on the insulation body 310 along the extending direction of the insulation layer 300. The rope passage tube 340 is sleeved on the pull rope 330. The rope passage tube 340 can prevent the pull rope 330 from directly contacting the insulation body 310, and can form a cavity for the pull rope 330 to move, thereby helping to protect the insulation body 310 and reduce the resistance of the pull rope 330 to pulling the support member 320.

[0087] Reference Figure 5 and Figure 7The insulation layer 300 includes multiple support members 320. The support members 320 are arranged at intervals along the extending direction of the insulation layer 300. It should be noted that... Figure 5 and Figure 7 The diagram only shows a portion of the extension direction of the insulation layer 300. The pull cord 330 is sequentially connected to each support member 320. The support members 320 are spaced apart along the extension direction of the insulation layer 300, allowing the insulation layer 300 to be bent at the midpoint between two support members 320, thus facilitating its storage. For example, during the storage of the insulation layer 300, a serpentine bend can be made using the midpoint between two support members 320 as the bending point. After the thickness of the folded body reaches a preset value, the insulation layer 300 can be stored by winding it around the folded body. The serpentine bend refers to: along the extension direction of the insulation layer 300, one of two adjacent bends folds in a first direction towards the thickness of the insulation layer 300, and the other folds in a second direction towards the thickness of the insulation layer 300.

[0088] Reference Figure 10 and Figure 11 In some embodiments, each support member 320 has a rope passage 340 between its two ends along its length. Exemplarily, when the support member 320 is in its second state, the two ends of the rope passage 340 can respectively abut against two connectors 323 at both ends along the length of the support member 320. This embodiment can limit the elastic deformation of the support member 320 through the rope passages 340 at both ends along the length of the support member 320, thereby preventing the support member 320 from being excessively deformed by the pull rope 330.

[0089] In some embodiments, the distance between two adjacent support members 320 is greater than the length of the rope tube 340 located between the two adjacent support members 320. In this way, the portion between two adjacent support members 320 where the rope tube 340 is not provided can be folded over to facilitate the folding or rolling of the insulation layer 300 for storage.

[0090] In some embodiments, the conduit 340 is a flexible tube. The distance between two adjacent support members 320 is equal to the length of the conduit 340 located between the two adjacent support members 320. In this embodiment, the conduit 340 being a flexible tube means that the conduit 340 is flexible but not axially compressible. For example, the conduit 340 can be a plastic tube with a lubricating layer on its inner surface. Specifically, the conduit 340 can be a polyurethane flexible tube or a polyvinyl chloride flexible tube. For example, the inner wall of the conduit 340 has a Teflon lubricating layer. In this embodiment, the insulation layer 300 can be folded or rolled up for storage by bending the conduit 340.

[0091] Reference Figure 3 and Figure 4In some embodiments, the PVDF membrane chamber of the sand and gravel system includes multiple inner wall tops 210. Each inner wall top 210 has a first connecting portion 211 and a second connecting portion 212 on both sides in the width direction. The first connecting portion 211 is connected to the inner wall of the outer wall top 220. The second connecting portion 212 is connected to the second connecting portion 212 of the adjacent inner wall top 210.

[0092] Reference Figure 3 In some embodiments, the width of the second connecting portion 212 is substantially equal to the thickness of the insulation layer 300. In other embodiments, the width of the second connecting portion 212 may be slightly smaller than the thickness of the insulation layer 300. Specifically, the difference between the width of the second connecting portion 212 and the thickness of the insulation layer 300 is less than or equal to 1 cm.

[0093] In the above embodiment, the connection method between the inner wall top 210 and the outer wall top 220 is beneficial to reducing the distance between the insulation layers 300 in two adjacent receiving cavities 201, and is beneficial to improving the insulation performance of the PVDF membrane chamber of the sand and gravel system. In addition, the second connecting portions 212 of the two adjacent inner wall tops 210 are connected, such as... Figure 4 As shown, this can prevent the first connecting part 211 from being torn along the surface of the connection and bonding with the outer wall top 220, thereby improving the reliability of the connection between the first connecting part 211 and the outer wall top 220.

[0094] This application provides a construction method for a PVDF membrane silo in a sand and gravel system, specifically a construction method for building a PVDF membrane silo. This construction method for a PVDF membrane silo in a sand and gravel system can be applied to the PVDF membrane silo in the sand and gravel system provided in this application.

[0095] Specifically, the construction method for the PVDF membrane chamber of the sand and gravel system provided in this application includes:

[0096] Step 1: Pour a concrete foundation with an anchoring structure for securing the top edge of the air-supported membrane wall.

[0097] During construction, a concrete foundation 100 can be formed on the ground according to the size and shape of the PVDF membrane chamber of the sand and gravel system. Specifically, the steel reinforcement skeleton within the concrete foundation 100 can be welded or connected to the anchoring structure at the top edge of the anchored air membrane wall.

[0098] Step 2: Lay the protective layer on top of the air-supported membrane wall.

[0099] Specifically, before the air-supported membrane roof 200 is installed, a protective layer is laid or wrapped on the ground or foundation surface to prevent sharp objects from damaging the air-supported membrane roof 200. For example, the protective layer may be, but is not limited to, at least one of foam, cotton cloth, or tarpaulin.

[0100] Step 3: Unfold the air-supported membrane structure on the protective layer at the top of the air-supported membrane structure.

[0101] For example, the air-supported membrane roof 200 can be deployed with the assistance of a crane.

[0102] In some embodiments, step 3, deploying the air-supported membrane structure on the protective layer of the air-supported membrane structure, includes:

[0103] Step 3.1: Deploy the top of the air-supported membrane wall in the first direction;

[0104] Step 3.2: Expand the top of the air-supported membrane wall in the second direction, with the first direction perpendicular to the second direction.

[0105] For example, in the first direction and the second direction, one is the length direction of the air-supported membrane wall top, and the other is the width direction of the air-supported membrane wall top.

[0106] Step 4: Secure the edge of the air-supported membrane wall to the anchoring structure of the poured concrete foundation.

[0107] For example, the edge of the air-supported membrane wall can be fixedly connected to the anchoring structure of the cast-in-place concrete foundation using angle steel plates and bolts.

[0108] Step 5: Inflate the space formed by the top of the air-supported membrane wall, the poured concrete foundation, and the ground.

[0109] Step 6: Insert the insulation layer into the cavity formed between the inner and outer layers of the air-supported membrane wall. Specifically, a crane and / or a ladder can be used to insert the insulation layer into the cavity.

[0110] Step 7: Secure both ends of the insulation layer.

[0111] Step 8: Pull the cord of the insulation layer to switch the support inside the insulation layer from the first state to the second state.

[0112] For example, the first rope 331 and the second rope 332 can be pulled simultaneously so that the forces at both ends of each support member 320 can cancel each other out, thereby helping to prevent the insulation body 310 from sliding relative to the top of the air film wall 200.
